Toa@ whom it may concern:

Be it known that We,EDW-ARD L. PEQUE- lnQUEeNAT, and CHARLES W.MIL\N,citizens of the United States, residing at Riverside, inthe vcountyofRiverside and State of California, have invented a improved'` yieldablenew ,and useful Motor-Cycle, of Which the fol* Vlowing is aspecification.

This invention relates to motor-cycles, and is designed to improve andsimplify the power-.transmitting mechanism between the motor and thedrive-Wheel of the cycle. In this connection it is proposed to providean power transmitting mechanism whereby excess motion dueto the.rapidimpulses of the motor are com ensated lor, thereby to preventslipping of the drive-Wheel tain a regular operation of the drive-Wheel.

. hereinafter from direction longitudinally n With these' and other.objects in view the present invention consists in the combination andarrangementof parts, as Willbe more fully described, shown in theaccompanying drawings, and particularly pointed out in the appendedclaims, it

`being understood that changes in. the form,- proportion,`siz e, andminor details may bem made Within the scope ofthe claims Withoutdeparting from the spirit or sacrificing any of the advantages ci theinvention.

1n the drawings, Figure 1 is a side elevation of a bicycle equipped withthe improve# ments ofthe present invention, the clutch of the'drivemechanism being shown in section.

Fig. 2 isa plan section on the line 2 2 of 1, with the clutch insection.

.Like characters of reference designate corresponding parts in' allofthe figures of the drawinvs.

Working within the drive member of the.clutch is the driven coni- '.cal clutch member 12, working infrictional' relation With the beveled face of the flange 10 and tubularin form to receive theforward end of the drive-shaft 13, which has itsrear end mounted lin' at the rear lower end of the'adjacent rear fork ofthe frame of the' bicycle. The clutch member 12 is fixed to the shaft,so as to ro-. tate therewith, and is capable of a limited slidablemovement thereon, preferably by means of a pin orkeyl 15, carried by theclutch member and Working-in a longitudinal slit 1.6 in the shaft. thereis a beveled-pinion 17 Ain niesh with a bevleled gear 18 upon the rearaxle of the bicvc e.

Upon the opposite side of the bicycle from the shaft 13 there is theusual sprocket-chain 19, running to the sprocket-Wheel 20, which isdriven by ordinary pedal-cranks 21 for use in Acontrolling the bicyclewhen vthe latter is uncoupled from the motor. j

For' throwing the motor into and out of operation there is an upstandingbell-crank or angular lever 22, fulcrumed upon a bracket 23, rovidedupon the seat-post tube 2e.l The o wer end of thi's lever is infrictional relation With the rear end ofthe clutch member 12, and to its'upper end is engaged a suitonnectirig-rod 25, which is h (Not showntrclled in any suitable manner. 1
